I rather prefer the Wren at the far right-hand end...
Dunno what lookers wings look like - what's that on the arm of the twoandahalfer seated three to the right of my OM, next to the pusser with the milkbottle specs? They look a different shape to the wings worn by the captain in the front row.
And comparing milkbottle's stripes with my OM's, it definitely appears to me that my father was still a Lieutenant there, which seems to confirm that this was while he was stationed at Daedalus, 43-45.
And why might the Commander between milkbottle and my Dad not be wearing braid on his cap?
